How do you know if a finite/infinite number sequence is a true random sequence?

Truly random sequences are normal.

You don't, for I can take any random sequence and copy it, making it completely deterministic.

The seed was completely random so no, it was not deterministic.

You determine its autocorrelation(k). If it is beyond an arbitrary number (for instance, often we use 0.2, but we can select for a lower one) we can say it is random enough
